Thomas Huth 77319f2263 s390x/virtio-hcall: Specification exception for illegal subcodes
So far, the DIAG 500 hypervisor call was only setting -EINVAL in
R2 when a guest tried to call this function with an illegal subcode.
This patch now changes the behavior so that a specification exception
is thrown instead, since this is the common behavior of other DIAG
functions (and other CPU instructions) when being called with illegal
parameters.

Thomas Huth f2c55d1735 s390x/virtio-hcall: Add range check for hypervisor call
The handler for diag 500 did not check whether the requested function
was in the supported range, so illegal values could crash QEMU in the
worst case.
